OK, a couple new rocks found - are any of these Agates?

[rockcrazy]

All of these rocks were found in my backyard/woods in Southern Michigan. The first one looks like it has agate like banding/swirls. It looks like it may be mixed with chert or flint??




Here is the next rock. This one has fossils on the exterior....



Last one.



I dug all these up in a patch of gravel in the same location. I'm hoping I have a honey hole

First one does look like some type of agate with quartz and something else conglomerate but very fractured. Second one....I don't know much outside of petrified wood for fossils so no idea. 3rd maybe jasper? Just my amature guesses

I must say that I don't see any of them as agates. Maybe granite and quartz. First one looks to me like granite.
